A77 (Upsize to 24Mp from 6Mp File Above by PS) at ISO100 Crop (1480x1480) (File Size:1.0MB)

Compare 24Mp vs 6Mp Upsized Image at ISO100 Crop (1480x1480) (File Size: 1.32MB vs 1.0MB)

The difference between the 24Mp crop vs the 6Mp Upsized image crop is minimal.

Higher resolution sensor will give a larger file size, but it is not necessary show more detail.

Noise reduction is applied at base ISO and it smooth out fine detail.

A lower resolution sensor with less noise, can provide as good as a higher resolution sensor, because it require less noise reduction.


If A77 can shoot at 6Mp, it can shoot 4~5 times longer before buffer full.

eg. 7sec, 85 RAW+Jpg at 12fps, Infinity Fine jpg at 12fps, etc.
